BUTTON OR STUD.

SBEGIFICATION forming part of Letters Patent No. 235,853, dated December 28, 1880.

Application filed October 13, 1880.

in the State of Rhode Island, have invented a new and Improved Button or Stud; and we do hereby declare that the following specification, taken in connection with the drawings, making a part'of the same, is afull, clear, and exact description thereof.

Figure 1 shows the back of the button. Fig. 2 is a vertical section through the post. Fig. 3 is a vertical section on aline at right angles with Fig. 2. Fig. 4 shows the blank from which the post and back are formed. Fig. 5 shows the blank after being formed into its proper shape.

Our invention relates to what is known in the market as a non-separable button, and has for its object the easy and convenient adjustment of the same, and rapidity and cheapness of manufacture; and it consists in the formation of a blank from a single piece of metal, as hereinafter described, and the subsequent bending of the same to form the back and post of the button, as hereinafter set forth.

In the drawings, A, Figs. 1, 2, and 3, is the outer rim of the button, within which the stone is held. B is the stone or front of the button. 0 is the back, which is first struck from a solid piece of sheet metal, as shown in Fig. 4., and consists of two half-circular disks, d d, having their adjacent straight sides connected together by a band, 6. The band c is provided. with a slot, F, and opening into the slot F, at each end i f the same, upon the under side of the back-blank 0, Fig. 4, are two grooves, g g.

The back-blank 0, having been constructed as described, is next bent into shape as shown in Fig. 5, which brings the half-disks nearly together, and forms from the band 6 a projecting loop or post, H. The bend being made across the center of the slot F, an open slot will be left in the end of the loop or post H, while the two grooves g y will cover each other and form a perpendicular channel from the bottom of the open slot the entire length of the adjoining surfaces. The projecting ears 0 c are drilled to receive a rivet which passes through a cam-lug upon the under side of the shoe J and secures the latter thereto. K is (No model.)

a pin working within the channel formed by the grooves g 9, one end of which rests upon a spring, L, and the other against a cam-lug upon the under side of the shoe J.

In putting the parts of the button together we first secure the stone or frontB within the rim A, then place the springL upon the back of the stone, and afterward place the back 0- within the rim, and secure by soldering, as shown in Fig. 1. The spring L is received within the narrow space between the two halfcircular disks d d. We next insert the pin K in the perpendicular channel formed by the grooves g g, and finally attach the shoe J.

The operation of my invention is as follows, taking the parts in the position shown in Fig. 1: In order to prepare the button for insertion in the garment, we turn back the shoe J with the thumb and finger until it reaches a point perpendicular and parallel with the post H, as shown by dotted lines, Figs. 1 and 3. During this movement of the shoe the camlug, through which the rivet passes to secure the shoe to the ears 0 0, acts upon and depresses the pin K, overcoming the resistance of the spring L. The shoe J and post H are now thrust into the buttonhole until the former passes through, when it is, by the pressure of the finger, brought back to its former position and the button is secured in place. To remove the button, the shoe J is brought again to its perpendicular position, when it may be easily withdrawn in a manner well understood.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The back 0 and post H of a button or stud made from a single piece of metal cut into the form of two nearlyhalf-circular disks, d d, connected together by a slotted band, e, substantially as described.

2. The combination of the back 0 and post H with the spring L, pin K, and shoe J, the whole constructed and operating together in the manner substantially as described.
